The synchro- nization signals may be multiplexed to form a SS block that is transmitted as part of an SS burst. Each SS block may be identifiable based on SS block index information carried by its corresponding synchronization signals. In one aspect, a synchronization signal that carries SS block index information is frequency division multiplexed with a secondary synchronization signal of the SS block. In one aspect, the synchronization signal that carries the SS block index information comprises a DM-RS for a PBCH of the SS block. A UE may use the SS block index information to identify a beam on which the SS block is transmitted. The UE may use the synchronization signals as part of a cell search procedure by which it acquires time and frequency synchronization with the base station.
